[libvirt] virsh blockresize syntax is inconsistent with vol-resize and somewhat dangerous
by Tim Small 23 Dec '19

23 Dec '19

Hello, virsh has two commands which can be used to resize block devices - "blockresize" for volumes in use by and active guest, and "vol-resize" for volumes which are not in use. The vol-resize syntax allows to specify the size as a delta (increase or decrease vs. the current size), and also refuses to shrink a volume unless the "--shrink" argument is also passed. Most other tools which can be used for block device resizing (outside of libvirt) also have similar "--shrink" argument requirements when reducing the size of an existing block device. e.g. ceph requires "--allow-shrink" when using the "rbd resize" command. The lack of such a safety device makes "blockresize" a foot-gun (which I recently found to great effect when I typoed the domain name to another valid domain). It seems I am not alone in making this error e.g. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=902171 One possible solution would be to make a new command e.g. "domblkresize" or perhaps "live-resize", which implement the "--shrink" and "--delta" behaviour to make it consistent with "vol-resize" syntax, and mark the "blockresize" command as deprecated in the documentation and help (so that existing automation which depends on the current behaviour doesn't break). Any thoughts? Should I open this as an RFE? Thanks, Tim. -- South East Open Source Solutions Limited Registered in England and Wales with company number 06134732.

[libvirt] [PATCH 1/1] qemu: hide details of fake reboot
by Nikolay Shirokovskiy 19 Dec '19

19 Dec '19

If we use fake reboot then domain goes thru running->shutdown->running state changes with shutdown state only for short period of time. At least this is implementation details leaking into API. And also there is one real case when this is not convinient. I'm doing a backup with the help of temporary block snapshot (with the help of qemu's API which is used in the newly created libvirt's backup API). If guest is shutdowned I want to continue to backup so I don't kill the process and domain is in shutdown state. Later when backup is finished I want to destroy qemu process. So I check if it is in shutdowned state and destroy it if it is. Now if instead of shutdown domain got fake reboot then I can destroy process in the middle of fake reboot process. After shutdown event we also get stop event and now as domain state is running it will be transitioned to paused state and back to running later. Though this is not critical for the described case I guess it is better not to leak these details to user too. So let's leave domain in running state on stop event if fake reboot is in process. As we don't know when stop event really arrive let's move resetting flag after starting CPUs - at this point stop event should be handled.

[libvirt] [PATCH 0/2] Deprecate implicit filters
by Vladimir Sementsov-Ogievskiy 22 Nov '19

22 Nov '19

Hi all! Max's series to fix some problems around filters consists of 42 patches. I'm sure that we didn't find all bugs around filters, and that filters would be a constant source of bugs in future, as during developing new feature nobody will consider all possible cases of dealing with filters (OK, somebody will, but it's hard). So, I'm thinking about starting some deprecations which will help us to simplify all the picture at least in not far future. So, I'd really want to deprecate implicit filters, ->file child based filters (move all filters to use backing child), filename based interfaces (use node-names). Most simple thing is implicit filters, so let's start from them. drive-mirror don't support filter-node-name, so I propose to deprecate it at all, together with drive-backup, instead of adding support of filter-node-name, what do you think?

[libvirt] [PATCH RFC 00/40] qemu: Add support for incremental backups
by Peter Krempa 22 Nov '19

22 Nov '19

This series is my attempt to clean up and finish incremental backup as it was last posted in v10 here: https://www.redhat.com/archives/libvir-list/2019-August/msg01018.html Out of that series, patch 1 was dropped for now and I'll revisit it later. The patches adding docs, xml parsing and job plumbing were partially modified and stripped of currently unimplemented functionality. The qemu implementation was completely rewritten. Of the new series first 28 patches are cleanups and can be reviewed for pushing. The main incremental backup functionality is not complete yet and should not be pushed right now not even in experimental (disabled [1]) state due to possible API changes: - figure out whether we want our own event for the backup job or want to deal with the domain job event - if we go with the domain job event everything must be rewritten as a single domain job - otherwise plumbing for the event must be added - documentation must reflect the above after that will be sorted out the following needs to be done until we can finally enable it: - more testing. I merely verified that qemu generates files/exports NBD - blockjob support for bitmaps (for commit/pull/copy) - snapshot support for bitmaps - merging of bitmaps accross backing chain entries - figuring out a more elegant way to do the bitmap for the backup than creating two, one for the 'store' (for NBD server) and one for the disk itself. - ... Until then the following XML can be used to enable the functionality for testing without any guarantee [1]: <domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'> ... <qemu:capabilities> <qemu:add capability='blockdev'/> <qemu:add capability='incremental-backup'/> </qemu:capabilities> </domain> Eric Blake (5): backup: Document new XML for backups backup: Introduce virDomainBackup APIs backup: Implement backup APIs for remote driver backup: Parse and output backup XML backup: Implement virsh support for backup Peter Krempa (35): util: hash: Add possibility to use simpler data free function in virHash util: hash: Add new constructor 'virHashNew' util: hash: Introduce virHashHasEntry qemu: domain: Split out setup of virStorageSource from qemu driver config qemu: domain: Remove pointless return value in qemuDomainPrepareDiskSourceData qemu: domain: clarify sematics of qemuDomainPrepareDiskSourceData qemu: domain: Tolerate NULL @disk in qemuDomainPrepareDiskSourceData conf: Remove virDomainDiskPathByName conf: Introduce virDomainDiskByTarget qemu: Replace use of virDomainDiskFindByBusAndDst with virDomainDiskByTarget conf: Remove unused virDomainDiskFindByBusAndDst Replace virDomainDiskByName by virDomainDiskByTarget in appropriate cases qemu: monitor: Introduce new interface to query-named-block-nodes qemu: block: Don't query monitor in qemuBlockStorageSourceCreateDetectSize qemu: checkpoint: Fix rollback and access to unlocked 'vm' when deleting checkpoints qemu: monitor: Remove non-transaction based dirty bitmap APIs conf: snapshot: Don't clear current snapshot when redefining an existing one conf: snapshot: Remove 'update_current' parameter from virDomainSnapshotRedefinePrep conf: Don't reuse variable for different object in virDomainCheckpointRedefinePrep conf: checkpoint: Don't clear current checkpoint when redefining an existing one conf: checkpoint: Don't clear current checkpoint when redefining qemu: checkpoint: Enforce that 'bitmap' name must match checkpoint name qemu: checkpoint: Split out checkpoint creation code qemu: checkpoint: Extract finalizing steps of checkpoint creation qemu: monitor: Add helper for generating data for block bitmap merging qemu: checkpoint: Use qemuMonitorTransactionBitmapMergeSourceAddBitmap qemu: blockjob: Refactor qemuBlockJobEventProcessConcludedTransition qemu: blockjob: Use 'g_free' in qemuBlockJobDataDispose Add 'backup' block job type qemu: monitor: Add support for blockdev-backup via 'transaction' qemu: domain: Track backup job data in the status XML qemu: blockjob: Track internal data for 'backup' blockjob tests: qemustatusxml2xml: Add test for 'pull' type backup job qemu: Implement backup job APIs and qemu handling qemu: blockjob: Implement concluded blockjob handler for backup blockjobs docs/docs.html.in | 3 +- docs/format.html.in | 1 + docs/formatbackup.html.in | 168 ++++ docs/formatcheckpoint.html.in | 12 +- docs/index.html.in | 3 +- docs/schemas/domainbackup.rng | 219 +++++ examples/c/misc/event-test.c | 3 + include/libvirt/libvirt-domain.h | 29 +- libvirt.spec.in | 1 + mingw-libvirt.spec.in | 2 + src/conf/Makefile.inc.am | 2 + src/conf/backup_conf.c | 518 ++++++++++ src/conf/backup_conf.h | 102 ++ src/conf/checkpoint_conf.c | 17 +- src/conf/domain_addr.c | 4 +- src/conf/domain_conf.c | 50 +- src/conf/domain_conf.h | 8 +- src/conf/snapshot_conf.c | 6 -
